South Korea's capital metropolitan area accounts for more than half of the country's total population and GDP. To overcome this phenomenon, the Korean government implemented various policies for the balanced development of the country, a representative of which was the construction of Sejong City in Chungcheong Province. Sejong City was established in July 2012, and by 2021, 44 government organizations and 15 state-run research institutes had migrated from metropolitan areas. In addition, it actively interacts with various cities in Daejeon, Chungcheongbuk-do, and Chungcheongnam-do, increasing its influence on the size of the economy and surrounding cities. Despite the importance of Sejong City, economic analysis after its establishment of Sejong City is still insufficient. Sejong City is expected to have clear regional characteristics in the public administration sector and research and development (R&D) for construction purposes. The education service industry is expected to revitalize because of the characteristics of the newly created city. Therefore, by using the 2015 Korean Multiregional Input-Output table, this study analyzes the industrial structure of Sejong City and Sejong's industrial characteristics and economic relations with other regions by measuring the industrial linkage between Sejong City and Chungcheong area, Seoul metropolitan area, and other regions by major industry.
